INVENTOR ATTORNEY Patented Apr. 14, 1942 UNITED STATES 'EHQ 'E'ET 1Claim.

(Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) This invention relates to anchorsand has for its object, among other things, to provide a light weightanchor of high-holding power and being so constructed as to be stowablein a very small space.

It is a further object of this invention to provide an anchor which,while possessing the foregoing characteristics, may be made by castingand thus be kept sufliciently strong to prevent bending of its membersduring normal use.

It is a further object of this invention to provide an anchor which mayretain the benefits of a stock and, at the same time, be capable ofbeing housed in a hawse pipe.

With the foregoing objects in mind, a clear understanding of theinvention may be had by a careful consideration of the followingspecification taken together with the accompanying drawing, in which:

Fig. 1 is a plan view of the anchor, and

vFig. 2 is a side elevational view of the anchor, showing inconstruction lines the position of the shank when the anchor is in theholding position.

The anchor consists of a shank 3, a fluke assembly and a stock I. Thefluke assembly is formed with a slotted crown from the sides of whichand integral therewith extend two arms 12 running parallel to the shankand terminating in a pair of flukes 4. One end of the shank 3 is securedfor pivotal movement in the slotted portion of the crown by means of apin H] which may be secured in one of the cheeks of the crown 5 by meansof a screw-threaded connection.

Extending from the crown 5 is an ear 6 having a hole running through itparallel to the hole carrying the pin I0. Through this hole is thrust astock I having its ends bent at right angles to its main part. The stockis secured against movement through the hole, when in use, by means of acollar 8 secured to the stock and normally held close to the ear 6 by aremovable pin 9 which passes through a hole in the stock on the otherside of the ear. The collar 8 is formed with a flat face I3 whichcooperates with a fiat face l4 formed on the top of the When in use theanchor is assembled as shown in full lines in Fig. 1. In dotted lines inthis figure is shown the stock I folded alongside the shank for stowage.In Fig. 2, the shank 3 is shown in dotted lines in the position itassumes when the anchor is in holding position on the bottom. Thelateral movement of the shank with respect to the flukes is limited bythe limits of the slot I5 in the crown 5.

While the provision of only one bent end of the stock is necessary forfolding the stock alongside the shank for stowage, both ends are bent inthe same manner in order to provide added stability when the anchor ison the bottom.

The invention described herein may be manufactured and/or used by or forthe Government of the United States of America for governmental purposeswithout the payment of any royalties thereon or therefor.

What is claimed is:

An anchor comprising a shank, a fluke assembly and a stock, said flukeassembly comprising a slotted crown, a pair of arms rigidly secured tosaid crown and extending substantially parallel to each other, each ofsaid arms terminating in a fluke, means securing one end of said shankfor pivotal movement within said slotted crown about an axis normal tothe longitudinal axis of said shank, means securing said stock to saidcrown for sliding movement therethrough along a line parallel to theaxis of said pivotal movement of saidv shank with respect to said crown,said stock being formed With both its ends bent to lie in the same planeand extend in a direction substantially normal to its length, and meansoperable at will to hold said stock against sliding movement with itsmid-point located within said crown and to hold said stock againstrotation with respect to said crown with its bent ends extending in adirection opposite to said arms, said stock when said holding means arerendered inoperative, being slidable through said crown to a foldedposition in which its central portion lies alongside said shank forpurposes of stowage.
